Intel® Server Board S2600CP and Server System P4000CP TPS Intel® Server Board S2600CP and Intel® Server System P4000CP Platform Management however, this may need to be comprehended by the fan monitoring FW if it does have this sideeffect. ME FW will log an event into the SEL to indicate when the system has been throttled by the SmaRT/CLST power management feature. This is dependent on ME FW support for this sensor. Please refer ME FW EPS for SEL log details. 6.6.4.1 Dependencies on PMBus*-compliant Power Supply Support The SmaRT/CLST system feature depends on functionality present in the ME NM SKU. This feature requires power supplies that are compliant with the PMBus Specification rev1.2. 6.7 EU Lot 6 Mode The European Union has set forth a stringent standby power consumption target for systems that are used as primary computing devices in office environments. Owing to the fact in office environments, pedestal servers are being used more and more as workstations and that Value servers could make their way into Home servers, this solution is being requested for some pedestal servers. HW support for EU Lot6 will only be available for specific pedestal products. In order to meet the standby power requirements for EU Lot6 it is necessary to remove power to the BMC, along with other components, when in the S5 state. As this operational mode impacts system feature support, the user has the option of enabling and disabling this mode by the BIOS setup screen utility. BIOS is responsible for enabling/disabling the system hardware for EU Lot6 operation. It notifies the BMC of the current state. The BMC saves the state in persistent store and uses it to control special EU Lot6 internal processing during boot, sensor monitoring, and so on as needed. Wake-on-LAN (WOL) is not supported in EU Lot6 mode. 6.7.1 Impact to System Features The following system features are lost or impacted when EU Lot6 mode is enabled:  Increased boot time (~15-20s) when system is DC power cycled. o This is due to the fact that both the BMC and BIOS are booting at the same time when the system is powered on (to S0 state). BIOS will need to allow extra time for the BMC to initialize to the point where it can communicate with BIOS. Note: Even when EU Lot6 is not enabled and the system is AC cycled, this increased boot time is applicable if a user immediately attempts to power the system up (for example, pressing the power button), as in this case both the BMC and BIOS are booting at the same time  No LAN manageability when on standby, and therefore no remote OOB power on by BMC.  No support for SOL or KVM for monitoring the entire boot process. o Since BMC is initializing at the same time as BIOS, it will not be possible to have an SOL or KVM session established from the beginning of the system boot.  FP status LED will behave differently (it will be off when on standby) rather than showing fault conditions present at the time the system was powered down.
